How To Clean Pee On a Mattress: Simple Steps That Really Work

If you’re searching for “How To Clean Pee On a Mattress”, you’re likely dealing with a fresh accident or discovering an older stain. This guide walks you through practical, at‑home methods to remove urine, reduce odor, and protect your mattress from long‑term damage.

What Happens When Pee Gets on a Mattress?

Urine can soak into the top comfort layers and even deeper into the mattress core. If it isn’t cleaned promptly and thoroughly, it can lead to:

  • Lingering odors
  • Visible yellow stains
  • Unpleasant sleeping surface

Because mattresses are thick and absorbent, surface wiping alone is not enough. The goal is to remove as much liquid as possible and then neutralize what’s left.

How To Clean Pee On a Mattress (Fresh Stains)

Step-by-step method for a recent accident

  1. Act quickly and blot, don’t rub

    • Use clean, dry towels or paper towels.
    • Press firmly to soak up as much urine as possible.
    • Avoid rubbing, which can push urine deeper into the mattress.
  2. Mix a gentle cleaning solution
    A common option is:

    • 1 part mild liquid dish soap
    • 2 parts cool water
    • Optional: a small amount of white vinegar for extra odor control

    Always spot-test on a hidden area first to make sure there’s no discoloration.

  3. Lightly apply the solution

    • Use a spray bottle if possible.
    • Mist the stained area until it’s damp but not soaked.
    • Let it sit for about 5–10 minutes.
  4. Blot again to remove moisture

    • Use fresh, dry towels to absorb the cleaning solution and remaining urine.
    • Press firmly and replace towels as they become damp.
  5. Apply baking soda for odor and moisture

    • Sprinkle a generous layer of baking soda over the treated area.
    • Gently pat it in so it contacts the fabric.
  6. Let the mattress dry thoroughly

    • Leave the baking soda on for several hours, or ideally overnight.
    • Improve airflow with open windows or a fan if possible.
    • Once dry, vacuum up the baking soda using an upholstery attachment.

If there is still a faint stain, you can repeat the process once or twice. Multiple light treatments are safer than one overly wet cleaning that soaks the mattress.

How Do You Clean Dried or Old Pee Stains on a Mattress?

Older stains are usually more stubborn because they’ve had time to set and dry. The general approach is similar, but you may need to:

Loosen the stain

  • Lightly spray the area with a mixture of:
    • Equal parts cool water and white vinegar
    • A small amount of mild dish soap if needed

Let it sit for 10–15 minutes, then blot thoroughly.

Repeat and be patient

  • You might need several rounds of spray, sit, and blot.
  • Each round can gradually reduce both the stain and odor.

Use baking soda overnight

  • After blotting, cover the area with baking soda and leave it on overnight.
  • Vacuum the next day to remove residue and help pull out deeper odors.

Can You Use Household Products Like Vinegar or Baking Soda?

Many people use everyday items to handle urine on mattresses. Common choices include:

  • White vinegar – Often used diluted with water to help neutralize odors.
  • Baking soda – Sprinkled on the damp area to absorb moisture and smell.
  • Mild dish soap – Helps break down residues on the fabric surface.

These are typically used in small amounts and well diluted, and always spot‑tested first. Strong chemicals, heavy perfumes, or large amounts of liquid are usually not ideal because they can damage fabrics or leave the mattress very wet.

How Do You Dry a Mattress Safely After Cleaning?

Drying is a critical part of How To Clean Pee On a Mattress effectively.

  • Increase airflow: Open windows, turn on a fan, or direct airflow toward the mattress.
  • Avoid direct high heat: Excessive heat can sometimes damage mattress materials.
  • Be patient: Make sure the mattress is completely dry before putting sheets back on.
  • Check both sides: If a large amount of liquid was involved, inspect the underside of the mattress for any dampness.

Sleeping on a mattress that is still damp can be uncomfortable and may lead to unwanted odors.

How Can You Prevent Future Pee Stains on a Mattress?

While accidents can’t always be avoided, you can make cleanup easier:

  • Use a washable mattress protector that fits securely.
  • Add a fitted sheet on top to create a second fabric barrier.
  • Keep extra sheets and protectors handy so you can change the bed quickly if needed.

A good protector can help keep liquids on the surface, so you’re cleaning the cover rather than the mattress itself.
